Abstract
Samples of seston, plankton and suprabenthic species were collected in the Seine estuary along the gradient of salinity (0 to > 30 PSU) duri ng six cruises from September 1992 to September 1995. Concentrations o f Cd, Cu, Pb and Zn were measured at different levels of the estuarian pelagic trophic web, such as organic detritus, diatoms, Copepods and suprabenthic organisms (mysids, shrimps and fish). Organic detritus, p hytoplankton and Copepods showed heavy metal contamination due to bioc hemical processes along the gradient of salinity, For carnivorous spec ies (shrimps and fish), this contamination may be found only for Zn an d Pb. No bio-magnification may be described in the trophic web of the Seine estuary. ((C) Academie des sciences / Elsevier, Paris.).
